399 In the
DART Forward Gain
list, select the dB (
0
to
31
), which is the actual gain, not
attenuation, that will be applied to the RF forward path signal (where
0
=
0 dB gain
,
1
=
1 dB gain
, and so forth) The DART Forward Gain is based on the EIRP desired
at the antenna. You therefore need to know how much cable, insertion, and any
other loss (such as splitters) exist between the Remote and the antenna. Set the
DART Forward Gain
to achieve the required output power level to meet the EIRP of
your RF link budget.
The following table provides calculations you need to set the gains to achieve the
desired Output power for a single-DART configuration.
For dual-DART configurations, you need to reduce each path by 3dB at the Remote
DART Forward Gain
. For example, for a DART Input Level of -25dBm, the Host FWD
Gain setting would be 31dB and the Remote FWD Gain setting would be 28dB.
